Definitions

  • the present invention relates generally to an ink cartridge assembly, and more specifically, to an ink cartridge assembly comprising an ink cartridge configured to store ink therein, and a cover member which covers an opening, such that when the cover member is removed, the cover member moves a sealing member away from the opening, which allows fluid communication between an interior and an exterior of the ink cartridge.
  • a known ink cartridge is configured to be selectively mounted to and removed from a known recording apparatus, e.g., a known inkjet recording apparatus.
  • the ink cartridge includes an ink chamber configured to store ink, and an ink supply portion configured to supply ink from the interior of the ink chamber to the exterior of the ink chamber.
  • a needle of the cartridge storage section is inserted into the ink supply portion, such that ink is supplied from the ink chamber to the recording apparatus.
  • the pressure in the ink chamber is less than the atmospheric pressure before the ink cartridge is mounted to the recording apparatus. Therefore, when the ink cartridge is mounted to the recording apparatus, ink may flow back to the ink chamber from the recording apparatus, and menisci of ink in nozzles of a recording head may be damaged.
  • the ink cartridge has an opening formed therethrough. The opening is closed by a sticker before the ink cartridge is mounted to the recording apparatus. Before a user mounts the ink cartridge to the recording apparatus, the user removes the sticker, which equalizes the pressure inside the ink chamber and the atmospheric pressure via the opening.
  • Another known recording apparatus has a mechanism configured to expose an opening formed through the ink cartridge, such that the pressure inside the ink chamber equalizes with the atmospheric pressure via the opening before the needle is inserted into the ink supply portion.
  • a known ink cartridge is described in JP-A-2007-55218 and JP-A-6-191046 , for example.
  • the mechanism may fail to expose the opening before the needle is inserted into the ink supply portion. Consequently, the pressure inside the ink chamber and the pressure outside the ink chamber may not be equalized before the ink cartridge is mounted to the recording apparatus.
  • a technical advantage of the present invention is that an opening of the ink cartridge readily may be opened when a cover member is removed from the ink cartridge before the ink cartridge is mounted to a recording apparatus.
  • an ink cartridge assembly comprises an ink cartridge comprising a body defining an ink chamber therein, and a sealing member.
  • the body has a particular face, and the particular face has a particular opening formed therethrough.
  • An interior of the ink chamber is configured to be in fluid communication with an exterior of the ink chamber via the particular opening, and the sealing member is configured to close the particular opening.
  • the ink cartridge assembly also comprises a cover member comprising a first portion configured to engage the body, and a second portion. The cover member is configured to attached to the ink cartridge and to cover the particular opening when the first portion engages the body.
  • the second portion When the second portion moves, the second portion is configured to apply a particular force to the sealing member to move the sealing member in a predetermined direction away from the particular opening and toward the ink chamber to allow fluid communication between the interior of the ink chamber and the exterior of the ink chamber, and is configured to disengage the first portion from the body.
  • the particular opening of the ink cartridge is readily opened when the cover member is removed from the ink cartridge before the ink cartridge is mounted to a recording apparatus.
  • the valve mechanism may comprises, a valve member and an urging member.
  • the urging member may be configured to apply a biasing force to the valve member to urge the valve member toward the particular opening, and when the second portion moves the second portion may be configured to apply the particular force to the valve member to move the valve member away from the particular opening against the biasing force.
  • the valve mechanism further may comprise a rod extending from the valve member in the predetermined direction, and when the second portion moves the second portion may be configured to push the rod to apply the particular force to the valve member to move the valve member away from the particular opening.
  • the ink cartridge further may comprises a movable member and at least one resilient member.
  • the movable member may be configured to move with respect to the body between a first position and a second position. A distance between the second position and the particular face may be less than a distance between the first position and the particular face.
  • At least one resilient member may be coupled to the particular face and to the movable member. The at least one resilient member may be configured to apply a further force to the movable member to urge the movable member into the first position.
  • the cover member When the first portion engages the body the cover member may be configured to position the movable member in the second position against the further force, and when the first portion is disengaged from the body the at least one resilient member may position the movable member in the second position.
  • the second portion may be configured to move relative to the first portion in the particular direction between an unoperated position and an operated position, and a distance between the unoperated position and the particular face may be greater than a distance between the operated position and the particular face.
  • One of the first portion and the second portion may comprise at least one slit formed therethrough, and the other of the first portion and the second portion may comprise at least one pin configured to be positioned within the at least one slit.
  • the at least one pin may be positioned within the second slit portion when the operation member is positioned in the unoperated position, and the at least one pin may be positioned within the first slit portion when the operation member is positioned between the unoperated position and the operated position.
  • the at least one slit further may comprise a third slit portion connected to a further end of the first slit portion which is opposite from the particular end of the first slit portion.
  • the third slit portion may extend in a direction which is substantially perpendicular to the particular direction, and at least one pin may be positioned within the third slit portion when the operation member is positioned in the operated position.
  • the first slit potion may extend in a direction which is inclined with respect to the particular direction. With this configuration, the second portion may rotate relative to the first portion when the second portion moves.
